How is an ISBN-13 barcode different from a Bookland barcode?
ISBN-13 and Bookland barcodes are both used on books and look the same. The difference is the structure of the ISBN number used to make them. The older Bookland symbol was based on 10-digit ISBN numbers and always began with “978”. The newer ISBN-13 symbols are based on 13-digit ISBN’s. While they begin with “978” now, as the “978” number space is exhausted, ISBN’s beginning with “979” will be used. Important: Do not use a 979 prefix until directed to do so by an ISBN standards body.
